To all whom it may concern-.-

Be it known that I, EDWARD S. a citizen of the United States, residingat ater-bury, in the county of New Haven and State of Connecticut, haveinvented a certain new and useful Improvement in Socket- Shells andGlobe Holders for Electric Lights, of which the following is a full,clear, and exact description.

The object of this invention is to enable a manufacturer or dealer tosupply the socket shells for electric lights in such way thatglobe-holders of any desired pattern may be applied to themexpeditiously and eco11oinically as desired, or the shells may be soldin SANnnnsoN,

dependently of the globe-holders.

1n carrying out the invention, the socket shell is made with acircumferential bead near its end, and the globe-holder is made with aninternal flange within which the beaded end of the shell is adapted tobe placed, and over the edge of which the beaded end of the shell may bespun, or otherwise turned expanded or upset, in order to connect theshell and holder in such way that there shall be no relative movement.

in the accompanying drawings, illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure l aninverted perspective view of one term of globe-holder; Fig. 2 is a perspective view of the socket shell. and Fig. 3

a longitudinal section of these two parts united. Fig; is an invertedperspective view of another form of globe-holder;- Fig. is a perspectiveview of the socket shell, and Fig. 6 1s a longitudinal section of thesetwo parts united. Fig. 7 is a perspective low of one form of holderhaving a plain flange.

The socket shell 1 has oneend made with a circumferential head 2,leaving beyond it a plain cylindrical extension v3; Such a shell is adated to be used with ordinary electric light c evices, and may be sold assuch.

In order that manufacturers or dealers may suit the desires or fanciesofpurchasers,

with respect to the style or finish orconstruction of globe-holder to beused on the selected style of socket shelhl provide the .globc-holder lwith the ordinary flange 5,

containin screws 6, as usual, to enga e the globe, an also provide saidholder with an the combined shell and globe-holder as shown in Fig. 7,this flange may be made made with the edge notches as previouslydescribed. The notchless flange shownin Fig. 7 is applicable to eitheror any form of holder.

In order to connect the socket shell with the desired globe-holder,itsbeaded end is inserted in the opening surrounded by the internalflange, and such end is enough longer than the depth of the flange toproject slightly beyond it, and when thus arranged, the projecting endof the shell is spun, expanded, headed up or otherwise upset or turnedover the edge of the internal flange, and if such edgebe notched, thistreatment causes the end of the shell to dig into said notched edge; ineither case, a very firni union or interlocking of the parts is secured.5

By the invention described, a manufacturer or dealer is enabled to usethe regular socket shell without any change if the globe holder iswanted on the socket. All that is necessary to fasten the socket andglobe,- holdcr together, is a small spinning tool and adrill press,although other machine or even hand tools may be employed for thispurpose. Moreover, the lobe-holder is held very firmly on the shel andthere is no chance of its becoming loose by relative rotary movement orotherwise; and finally, present a very neat appearance.

The circumferential head on the socketshell serves to limit the extentto which the shell projects within the internal flange, and to thisextentand in this manner serves as a stop. The invention, however, isnot: limited to the use of such bead.

The drawing, shows the notches 8 some what exaggerated in depth, andthis is done merely for illustrative purposes. In actual practice thesenotches need be but quite shallow, so long as they present surfaces orpertions capable of being engaged by the spun over or headed up edges ofthe shell; and as already stated, the internal flange maybe made Withoutnotches in its edge.

What I claim is 1. A socket shell and globe-holder for electric lights,comprising a shell, and a globe-holder having an internal flange, theshell adapted to be inserted within said flange with its thus insertedend extending beyond the inner edge of said internal flange and the edgeof the extended portion of the shell turned over and thus interlockedwith the flanges edge.

2. A socket-shell and globe-holder for electric lights, comprising ashell, and a globe-holder having an internal flange provided with edgenotches, the shell adapted to be inserted Within said flange andprojectbeyond its inner edge and its edge turned over and interlockedwith said notches, whereby relative rotary movement of the shell andholder is prevented.

3. A socket shell and globe-holder for electric lights, the shell havinga beaded end to limit its inward movement with relation to theglobe-holder, and the globeholder having an internal flange providedwith a notched edge, the beaded end oi the shell adapted to be placedwithin the internal flange so that its inner end projects beyond theedge of the flange and the edge of said projecting end turned over andengaged with the notched edge of said internal flange, whereby relativerotary movement of the shell and holder is prevented.

4. A socket shell and globe-holder for electric lights, comprising ashell having one end provided with a stop, and a globeholder having aninternal flange with a notched edge, the stop end of the shell insertedwithin the internal flange and its said inserted end extending beyondthe edge of the flange and the shells edge turned over and therebyengaged with the notched edge of said flange, whereby relative rotarymovement of the shell and holder is prevented.

In testimony whereof I have hereunto set my hand this 17th day of MarchA. D. 1910.

EDWARD S. SANDERSON.
